Aircraft Voltage Regulator Troubleshooting

Use the troubleshooting guide for repairs on our aircraft alternators.

Aircraft voltage regulator troubleshooting.

Most aircraft voltage regulators used today are solid state and no longer have the trouble prone contact points and coils. Need help solving an electrical system issue. If it does the generator is o k. The following applies to plane power r1224 voltage regulators.

Verify both the input and output voltage of the regulator. Voltage regulator troubleshooting tips. The voltage on the armature post should follow the throttle. Aircraft alternators are externally regulated by a voltage regulator sometimes called an alternator controller which is usually mounted either on the firewall in the engine compartment or under the instrument panel.

This video provides the basic steps for troubleshooting aircraft electrical system issues including headset noise. Which in turn decreases alternator output voltage. Normal readings should be around 14 volts for a so called 12 volt system. Make sure that when the master switch is on that you have battery voltage of at least 12 or 24 volts on the regulator battery terminal.

Good grounding eliminates many potential problems. Check the two wires from the generator to the voltage regulator. If another manufacturer s voltage regulator is installed refer to their maintenance manual. If the g the kelly aerospace vr2000 offers built in troubleshooting diagnostics to identify elec trical system problems all the while.

Check and record voltage of aircraft bus. Generation regulator incorporating gfp the voltage regulator will not be damaged and the gfp circuitry will take the electrical sys tem off line instantaneously precluding air craft wiring or avionics damage. Record aircraft bus voltage. The input voltage should be approximately the same as the bus voltage.

As such regulator maintenance other than basic adjustments are minimal.
